    Its simple. First ionization energy experiment for Group 1. They are different sub-shells for electrons to fill like sub-shell s, p, d, f, & g.

    Way is the first ionization energy experiment for group 1.

    Electron subshells are a name for a group of atomic orbitals. Atomic orbitals are the 'indivisible' unit you should look at. They are a region of space to which an electron/a pair of electrons if confined, as mapped out by a probability density.

    Evidence for them...... Well they fall out of quantum mechanics just like so much of the natural world, but there is experimental evidence. They elegantly explain the bonding in molecules and crystalline solids. Electron density plots can be formed (I think this is from X-ray spectroscopy... I'm not a physicist) and they match predictions from this theory)

    Actually electron subshells are a location where electron density is maximum. One or more orbitals in the electron shell of an atom with the same energy level. Subshells have different shapes and are distinguished by their magnetic quantum number. To check out the reason behind their existence just redirect to chemistryhomeworkhelp.biz
